我曾经用反射来提取水晶报告所使用的 sql 查询。 然后,我用这个提取的 sql (非常小心) 来填充数据集, 然后通过 SetData 源代码方法将该数据集与我的 ReportDocument 对象绑在一起。 所有这一切都很顺利, 但每当我试图查看或导出我的报告时, 它要求我提供我的证书/参数值, 这违背了人工查询/ 约束我数据的目的 。
当我的报告数据被挤进报告时(即我能否让报告不直接从数据库中刷新空格? )我曾经尝试设置“保存数据”值,但似乎没有帮助。
能否帮助:
ReportDocument cryReportDocument = .......;
cryReportDocument.SetDatabaseLogon("userName", "password");
cryReportDocument.SetParameterValue("parameterName", value);
CrystalReportViewer1.ReportSource = cryReportDocument;
